Plot I vs Q using complex matrix dataset

I want to plot I (inphase) vs Q (quadrature) graph using 128*256 complex dataset. The dataset is attached(M2.mat). What is the shape of the graph? Please share the code.

What about surf?

[Maximilian Schönau]

how do you want the komplex data be displayed? You need four dimensions to plot a 2d matrix of complex and therefor 2d numbers

As per my understanding you want to plot I and Q from the complex signal mentioned in M2.mat.

Following piece of code will help to achieve it.

load M2.mat; %load the M2 file to the workspace

I = real(M2); 
Q = imag(M2);

figure; hAxes = gca;
plot( hAxes, I );
hold( hAxes, 'on' );
plot( hAxes, Q, '--' );

Hope this helps
